l Application filed April 21, 1894:. Serial No. 508,482. (No model.) I

To. @ZZ whom,V 1f/,may concern:

Be it known that I, VJosmrrr C. WALTER, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Machines for Molding Qonfections, of4 which thefollowing, taken inrconnection with the' accompanying draw- Thisinvention relates tothe class of maf chines which are provided with ahopper for containing the material from which theconfection-drops are tobe formed. Said hopper being provided in its bottom with dischargespouts through which the aforesaid material is forced by plungers to themolds placed under the hopper.

The invention consists in an improved construction and combinationofparts constituting a confection molding machine of great eiiciency inits operationA and whichis'adjustable to mold confections of dierentsizes' as may be desired, all as hereinafter'more fully described andspeciiically set forth in.. the claims. ,4 l

The invention is fully illustrated in the annexed drawings, in which-Figures 1 and 2 are elevations of opposite sides of a confectionmoldingy machine embodying my invention Fig. 3 is a jverticallongitudinal section on line a-X--X-` in Fig. 4. Fig. Il is a verticaltransverse section on line -fJ--yin Fig. 3 andrFig. 5 lis a hori- Fig.3.Y.

-A-frepresents the base of the, machine, 4said base consisting oftwostout parallel Walls of castiron or otherjsuitable material. On theinner sides of these walls arev horizontal guides -ct-a.- for supportingthe trays -T- which contain themolds in which the per -Bw and frame -C-which latter extends above the hopper for the purpose hereinafterexplained. The hopper is formed of hollovvmetallic walls forming ajacket p-f-J- which is charged either with steamI or hot gaboveandbelowsaid frame.

water or hot air to heat the contents of the hopper and maintain thesame in proper condition for being molded. The bottom -B` of the hopperis provided with discharge-openings `cc and from these openings extendupward, thegage-tubes -d-dwhich are firmly secured to the saidbottonrand are provided with ports d-din their sides. O verthesaid tubesslide telescopically'- the .tubular valves ,-ewhich are fastened attheir upper ends to a horizontal plate -.D-

and receive intermittent reciprocating m0- tion by means ofpitmen-E-E'connect ing the plate -D- to arms -F--F- extending fromrock-shafts -A-G-G- over opposite ends of the hopper. Said rock-shaftbeing i operated automatically with other actuating mechanisms of themachine as hereinafter described. On the bottom of the hopperr is thelongitudinallyV movable gate -H for opening andclosing at the `propertimes the discharge openings c-c-n Said. gate being also operatedautomatically as hereinafter described.

In .thel gage-tubes -ddare plungers -fwhich are connected to ahorizontal skeleton frame I and receive reciprocating.

motion from rock-shafts -I-I- from Which extend arms ,-K-K- which areconnected with the frame-I- `by pitmen k-J-.

In order to permit the machine to be adjustedforforming confection dropsof different sizes, I lconnect the plungers to the 1 frame r-I-adjustably so as to vary the lengths of the strokes of said plungers.For 4 this purpose I prefer to connect the plungers to the frameA bymeans `of screw-threaded stems ff"- which pass through eyes in the framef-I- and are provided With nuts ,-g-

` By loosening one or both nuts on the stem so as to produce a lostvertical motion between the' stem and frame, the stroke of the plungercon-y nected to said stem is reduced and the quantity'of material forcedthrough discharge"v opening -cis correspondingly diminished.

In the operation of the machine, the gate -H- is closed and the valves-e-eraised to open the ports d d IOO Then the plungers -fare raised andthis4 causes 2 the confection-material to be suckedv through theaforesaid ports into the gage-tubes -dretain the material in the bottomportion of the tubes. Then the gate -H- is opened and the plungers-fpressed down to force the material from the tubes d-ddown into themolds contained in the trays y denote cam-wheels attached to thedriving` To the frame -C- are fastened two brackets `-h---h to one ofwhichis pivoted a lever -N- which has its upper end connected by apitman -P- to an arm -P on one of the rock-shafts -I- which actuate the'plungers -f-f-, by means of the frame -I'-. The opposite end of saidlever engages the cam -L- whereby it receives an oscillatory motionwhich is transmitted to the rock-shaft -I- by the pitman -eP-.Intermeshing gears -R-R* of equal sizes are attached to the tworock-shafts -l-I- to cause them to operate in unison. In order to allowrthe motion of said rock-shafts to be adjusted to impart longer orshorter strokes to the frame -I- which carries the plun gers, I slot thearm -P- longitudinally as shown at -1'4- in Figs. l and 2 of thedrawings, for the reception of the coupling pin, u. To the other bracket-hhereinbefore referred to, is pivoted a lever -=N- one end of whichengages a cam -L attached to the driving shaft -'O, by which it receivesan oscillatory motion. The opposite or lower end of said lever isconnected to the gate -H- to move the same so as to open and close thedischarge openings ccof the hopper -B-.

In order to cause the valves eeto open the ports -'d'-d eithersimultaneously with or immediately after the closing of the dischargeopenings` -c-c-, I employ suitable mechanisms driven primarily by themain driving shaft -O- and transmitting intermittent motion to therock-shafts -G- G. One simple form of said mechanism is shown by fulllines in the drawings and consists of cam-plates -Z-Z- attached to thegate II-'- and during the movement of said gate imparting reciprocatingmotion to pitmen -j-#j-e engaging said cam-plates and connected to larms'-n-'nattached to the rock-shafts -G--G-- Another form of said.mechanism is indicated by dotted lines in -0- mounted on the drivingshaft O and engaging the lower end of a lever pfulcrumed on the frame-C-, the upper end of which lever is connected to an arm -ron one of therock-shafts -G- and a rod '-tconnects said arm to an arm -rwhich isfastened to the other rock-shaft -G-.

It is obvious that the means for transmitting motion from the drivingshaft -O- to the gate H-, valves -e-e-- and plungers -f-fis susceptibleof numerous variations and I therefore do not limit myself to thespecifc mechanisms herein shown and described.

The operation of the described machine is 'f-fto be raised and therebyproduce a suction in the tubes -.-0Z-cZ- which draws theconfection-material into said tubes. Then the valves --edescend andclose the ports -cZ-d'- and immediately thereafter the gate -H- opensthe discharge openings -c-cand the plungers descend and force thematerial out of the tubes from whence said material drops into moldscontained in the trays -T-. This operation is repeated in the same orderand while the gate -H- is closed, another tray containing empty molds isplaced under the hopper B to receive the next discharges ofconfection-material.

What I claim as my invention i sl. In combination with the hopperprovided with discharge openings 'in its bottom, tubes extending upwardfromsaid openings and provided with ports in their sides, valves openingand closing said ports, plungers in said tubes, and a gate movableacross the discharge openings as vset forth.
